Engine cylinder sleeve non-destructive press-in device

Abstract

The invention relates to an engine cylinder sleeve non-destructive press-in device. The engine cylinder sleeve non-destructive press-in device comprises an upper supporting plate and a lower supporting plate; the lower supporting plate is disposed under the upper supporting plate in parallel; a supporting sleeve pipe is connected to the centers of the upper supporting plate and the lower supporting plate in a vertical penetrating mode; a pressing-down threaded rod is in threaded connection to the inner side of the supporting sleeve pipe; a pressing-down block is vertically and rotationally connected to the bottom end of the pressing-down threaded rod; a bearing is embedded into the center of the top of the pressing-down block; and the bearing is mounted at the bottom of the pressing-down threaded rod in a sleeving mode. The engine cylinder sleeve non-destructive press-in device is simple in structure, stable, reliable, easy and convenient to operate, capable of saving time and labor and convenient to use; and positioning can be performed fast and accurately, a cylinder sleeve is pressed in stably and safely, the press-in efficiency of the cylinder sleeve is improved, wood chips orcopper chips can be prevented from falling into an engine, the interior cleanliness and using performance of the engine are substantially improved, the effect that the cylinder sleeve is not damaged is guaranteed, the press-in efficiency is improved, the cylinder sleeve is stressed uniformly, the press-in quality is improved, and the application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of engine cylinder liners, in particular to a non-destructive press-in device for engine cylinder liners. Background technique [0002] The cylinder liner of the engine block is the key part of the engine. When the engine is working, the piston reciprocates in the cylinder. In order to improve the wear resistance of the cylinder bore of the cast iron cylinder block, a thin-walled steel sleeve is pressed into the cylinder bore. The pressed thin-walled steel The sleeve has high hardness, high surface quality, and high wear resistance, which greatly improves the life of the engine. However, it is difficult to press fit such a thin-walled cylinder liner. Improper pressing will cause serious deformation of the inner hole of the cylinder liner. Crush the cylinder liner, which will cause waste and affect the performance of the engine. When installing the engine cylinder liner, directly hit it with a wooden hammer o...

[0002] The cylinder liner of the engine block is the key part of the engine. When the engine is working, the piston reciprocates in the cylinder. In order to improve the wear resistance of the cylinder bore of the cast iron cylinder block, a thin-walled steel sleeve is pressed into the cylinder bore. The pressed thin-walled steel The sleeve has high hardness, high surface quality, and high wear resistance, which greatly improves the life of the engine. However, it is difficult to press fit such a thin-walled cylinder liner. Improper pressing will cause serious deformation of the inner hole of the cylinder liner. Crush the cylinder liner, which will cause waste and affect the performance of the engine. When installing the engine cylinder liner, directly hit it with a wooden hammer or a copper hammer. The cylinder liner is not installed correctly, and the cylinder liner is damaged to a large extent. At the same time, some wood chips or copper chips are easy to fall into the engine, affecting the cleanliness and performance of the engine. This is far from meeting the current people's requirements for this product.
